QUESTION
Is anyone else finding MIDI messages being dropped? Specifically, noteOn's not being followed by noteOffs and vice versa.
I've tried using both Android M's built-in API, MidiManager, and https://github.com/kshoji/USB-MIDI-Driver. And I've tried it on two Android devices.
Attaching the same piano to my computer yields no dropped messages.
Unfortunately, the piano streams MIDI spec Active Sensing messages (0xFE), which I think might not help. But it is a little disconcerting that any messages be dropped. My next step is to buy a separate MIDI to usb adapter instead of using the piano's usb output.
Any advice would be welcome
